2nd EDITION
The CNB SWIM returns for its second edition with a clear goal: sea, meters, and attitude. An open water swim organized by the Club Natació Barcelona and Radikal Swim, designed for swimmers seeking a real challenge in one of the city’s most iconic settings, Barceloneta.
The challenge is straightforward: 3.2 km in open sea. Just you, the Mediterranean, and a demanding course that requires endurance, control, and focus. A swim to push yourself, maintain your pace, and finish with the feeling of a job well done.
And when you finish, the CNB SWIM experience continues out of the water.
The afterswim is part of the event’s DNA: paella to recover your strength, a live DJ, and a party to share the experience with the other participants and close the day properly.
If you love the sea, clear challenges, and events with character, this is the swim for you.
Moreover, the CNB SWIM is part of the Catalan Open Water Circuit (CCT) of the Catalan Swimming Federation, included in the official calendar of open water events.
